Му́ки are a type of flour made from ground grains, commonly used in baking and cooking. They can be derived from various sources, including wheat, rye, and corn. The most common type is пшеничная мука, which is made from wheat and is essential for making bread, pastries, and pasta. Different types of муки have varying protein content and gluten levels, affecting the texture and structure of baked goods. For example, цельнозерновая мука is made from whole grains and contains more fiber, while мука высшего сорта is finely milled and has a higher gluten content, making it ideal for yeast breads.
